BREAD-DELIVERING moms.

To all whom. it may concern Be it known that I, James H. BLY'rHn, acitizen of the United States, and a resident of Denver, in the county ofDenver and State of Colorado, have invented a new and ImprovedBread-Delivering Machine, of which the following is a full, clear, andexact description.

This invention relates to dispensing apparatus and has particularreference to devices of the nature indicated which are adapted for thestorage and display of sliced bread, crackers, sandwiches or the like,and having provision for the delivery of such commodities singly by anauthorized person.

Among the objects of the invention, therefore, is to simplify andimprove the construction of devices of this character, having referenceespecially to neatnessand attractiveness of appearance, sanitation andreliability of operation.

The foregoing and other objects of the invention will hereinafter bemore fully set forth and claimed and illustrated the drawings forming apart of this specification in which like characters of reference in--dicate corresponding parts in all the views, andin which-'- I Figure 1is a perspective view of a device made in accordance with thisinvention, a major. portion of the display casing being removed; Fig. 2'is a vertical longitudinal section on the broken line 2-2 of Fig. 3;Fig. 3 is a horizontal section on the line 33 of Fig. 2; Figs. 4 and 5are transverse sections on the lines and 5-5 respectively, of Fig. 3;Fig 6 1 s'av1ew corresponding to Fig. 2 but indicating on -a largerscale the ejector n echamsmm normal position; Fig. 7- is a sim lar viewindicating the same mechanism in actuating position; and Fig. 8 is aperspective view of the rear end of one of the actuating bars.

The several arts of this device may be made of any suitable materials,and the relative sizes and proportions, as well as the general design of.the mechanism. may be varied to a considerable extent without departingfrom the spirit of the invention hereinafter more fully set forth andspecifically claimed.

Referring to the drawings for a more spe-v cific description, I showat-lO a base plate substantially fiat and having at the front end anupturned. flange 11 and in the bot- Specification of Letters Patent.

cured to the flange 11 by any suitable detachable means such, forinstance, as a screw 15 whereby the casing 13 is normally locked to thebase 10, the main portions of the casing being engaged beneath saidcatches 12 through transverse supports or bars 16 and 17 shown best inFig. 3.

At 18 I show another cross bar secured to the intermediate portion ofthe base casing, stiffening the same, and extending thence upwardly areside bars or standards 19 having a cross bar 20 connecting their upperends. An angle'member 21 may cooperate with the uprights 19 and crossbar 20-to secure the front panel 22 of the display casing in position.The upper surface of the easing 13 --issubstantially flat and smooth andis provided with a removable slotted panel 23, the slots 23 thereofbeing arranged parallel to one another and longitudinally of the casing.Said panel extends substantially through one half of said casing at therear end thereof. As shown in Fig. 2, the display casing comprises sidepanels 24:, a rear panel or side 25, and a top 26.'in

addition to the front panel 22 above described. The display casing,therefore, is intended to receive and hold for delivery a quantity orpile of. slices of bread or the like, indicated at A, to be dispensedsingly from the device through an opening 27 at the bottom of the frontpanel. Adjacent said opening is a flap 28 hinged on a horizontal pivot29 at or near the lower edge of the panel 22. Said hinge is carried byan adjustable guard 30 connected, by slotted flanges 31 to the innerfaces of the standards 19 as by set screws 32. Said guard 30 isadjustable vertically in accordance with the thicknessof the variouscommodities to be dispensed.

The ejector mechanism is located beneath the floor of .the device orupper portion of the-casing 13,.and includes a rock shaft 33 journaled'transversely of the casing and having a plurality of fingers'34, shownas five in number and adapted to project upwardly through the slots 23of the panel 23 during the forward actuation of the ejector. The saidrock shaft is journaled at 35 in a carriage 36 which is adapted toslideto and fro along a pair of guide bars 37 closely be low the top of thecasing 13. The rear ends of the guide bars 37 are connected to a crossbar 38 at the rear end of the casing and against which cross bar thecarriage 36 normally rests. At 39 I show a spring tongue connected tothe carriage and extending rearwardlyand upwardly into engagement thepurpose of ejecting a slice of bread. For

this purpose I prefer to employ a peculiar construction of actuating bar40 having rack teeth 41 throughout the length of one side thereof, andalso provided with a short series of teeth 42 at the top of its rear.end.

-Said bar 40 lies in and is guided along a channel member 43 which liessubstantially along the longitudinal center of the machine, The frontend of the actuator bar 40 lies normal-1 adjacent a gear 44 journaled at45ton'a vertical axis, the teeth 41 mesh- 7 ing with the teeth of thegear 44. The gear is operated by means of another rack bar 46 lying andoperating in a channel member 47 parallel .to the member 43 and adjacentone side of the casing 13. The rack 46, however, .is maintainedinposition adjacent the front of the casing by virtue of a spring 48acting upon the gear 44 as shown in Fig. 3.

At 49 I show a hand lever pivoted at 50 to one of the standards 19. Thisis shown as a lever of the first class, having at its rear end a link 51constituting an attachment means for a flexible connectionsuch as asteel ribbon 52 or the like, operating over a roller 53 and having itsforward end connected at 54 to-the rear end of the rack 46.

The roller 53 is journaled in a bracket 53 adjacent the bar 38. Theforce ofthe spring 48 acts, therefore, to hold the leverin the full lineposition of F i 2.

A gear segment '55 1S keyed to the rock shaft 33 and its teeth are inconstant mesh with the short-series of teeth 42 ofthe actua-- throughits teeth 42 to partiallyrotate the shaft 33, bringing the fingers 34 mmtheir normal position up to the position shown in Fig. 7. The carriage'36 during this time is notmoved, but as soon as the rotation of therock shaft is stopped by contact between the fingers 34 and theshoulders 36' of the carriage, the continued movement of the bar 40 willcause a positive reciprocation of the carriage, the fingers 34 beingheld in their projected position by virtue of the gear 55. Said fingers,therefore, will engage a slice of bread or the like and cause it to beprojected through the opening 27 and delivered upon the front portion ofthe casing 13'. The flange 11, however, preferably projects far enoughupwardly to prevent said commodity fromvbeing'ejected beyond the casing.As soon as the force of the operators hand is relieved slightly fromdownward pressure upon the handle 49, the first effect of the spring isto cause a reverse reciprocation of the actuating bar 40 .with theresult that the rock shaft and fingers will be rotated so as to bringthe-fingers below the slots 23, and therefore,while the fingers continueto restore the parts to normal position, there will be no engagementbetween the fingers and the commodity within thedisplay casing.

Any suitable number of guides 56 may be employed in connection with thechannel members 43 and 47 to hold the actuating racks therein.

Having -thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a device of the character set forth, thecombination of a display casing adaptedto hold a quantity of anycommodity to be dispensed, an actuator casing supporting the aforesaidcasing, the latter casing having a slotted top upon which the commodityrests, an ejector mechanism including a carriage, a rock shaft journaledto the carriage, a series of fingers carried by the rock shaft, andmeans to operate the rock shaft to first rotate the same to project thefingers into engaging position through the slots and subsequently tocause the carriage with the rockshaft to move longitudinally for thepurpose set forth.

2. In a device of'the character set forth, the combination of a casinghaving a slotted upper surface, guide means below the upper surface, anejector comprising a casing slidable along said guiding means, a rockshaft connected for partial rotation on said carriage and movabletherewith along the guiding means, engaging means carried by the rockshaft and adapted to be projected through the slots, and means actingupon the actuator serving first to rotate the rock.

shaft and subsequently topropel it and the carriage along the guidingmeans.

3. In a device of the character set forth, the combination of a casinghaving a series ef parallel longitudinally arranged slots in ts uppersurface, guiding means below said means, a series of fingers associatedwith I said carriage, and means acting upon said carriage to reciprocateit along the guiding means, the last mentioned means serving first toproject the fingers upwardly through the slots and subsequently to causethe positive movement of the carriage.

4. The herein described actuating device for a dispensing machine, thesame comprising guiding "means, a rock shaft arranged transversely ofthe guiding means, fingers connected to the rock shaft, an actuating barslidable longitudinally of said guiding means, means to reciprocate thebar, said bar acting first to partially rotate the rock shaft to elevatethe fingers and subsequently to carry the bar and fingers bodily withthe bar, and means to limit the eX- tent of rotation of the rock'shaft.

5. In a device of the character set forth, the combination of a casinghaving a series of parallel slots in its upper face, guiding meansbeneath said casing face and parallel to said slots, said guiding meansincluding a pair of channel members, a gearhwheel journaled between saidchannel members, a pair of actuating bars located and slidable in saidchannel members and having teeth meshing with the teeth of the gearwheel, means to reciprocate one of said bars to cause the rotation'ofthe wheel and the reciprocation of the other bar in the oppositedirection, the last mentioned bar having a short series of gear teeth onthe upper surface of its rear end, a rock shaft, a series of fingersconnected to the rock shaft and projectable upwardly through andguidable along said slots, a pinion connected to the rock shaft andmeshing with the short series of rack teeth, means to limit the rotationof the rock shaft, and means to restore the parts to normal positionafter actuation thereof.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
